cpupower: remove stringop-truncation waring
The strncpy doesn't null terminate the string because the size is too
short by one byte.
parse.c: In function ‘prepare_default_config’:
parse.c:148:2: warning: ‘strncpy’ output truncated before terminating
nul copying 8 bytes from a string of the same length
[-Wstringop-truncation]
strncpy(config->governor, "ondemand", 8);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The normal method of passing the length of the destination buffer works
correctly here.
Fixes: 7fe2f6399a84 ("cpupowerutils - cpufrequtils extended with quite some features")
